DESCRIPTION
HCF40162B is a monolithic integrated circuit
fabricated in Metal Oxide Semiconductor
technology available in DIP and SOP packages.
HCF40162B is a 4-bit synchronous programmable
counter. The CLEAR function is synchronous. A
low level at the CLEAR input sets all four outputs
low on the next positive CLOCK edge. A low level
at the LOAD inputs disables the counter and
causes the output to agree with the set-up data
after the following CLOCK pulse regardless of the
condition of the ENABLE inputs. The carry

look-ahead circuitry provides for cascading
counter for n-bit synchronous application without
additional gating. Counting is enabled when both
the PE and TE inputs are high. The TE input is fed
forward to enable COUT. This enable output
produces a positive output pulse with a duration
approximately equal to the positive portion of the
Q1 output. This positive overflow carry pulse can
be used to enable successive cascaded stages.
Logic transitions at the PE and TE inputs may
occur when the clock is either high or low.
